[Class 123 (iii)] In an independently-fired superheater comprising a convectively heated section 10 in a flue 2 separated from the combustion chamber by a refractory partition 3, radiantly heated superheating tubes 9 are disposed adjacent the roof of the chamber and continued down one or more of the walls of the chamber to protect the walls and to cool the furnace gases to a safe working temperature before contact with the convectively heated section. Tubes 9 extend from the inlet header 6, Fig. 1, up the front wall of the combustion chamber and across the roof, then some are bent and extended down the partition 3 and others are disposed along the rear wall of the flue 2 and all are connected to a rear header 7. The sinuous tubes of the section 10 are connected to the header 7 and to the outlet header 8. The steam may be directed through the sections in parallel instead of in series. The slabs forming the partition 3 may be supported partly on one side of the tubes 9 and partly on the other side. All the tubes 9 may extend down the partition 3. In a modification, the combustion chamber is lined on both sides with separate groups of tubes extending beneath the roof, and the partition is protected by a separate group of tubes. In this modification, the convectively heated section consists of two groups of sinuous tubes extending horizontally from adjacent headers. The tubes 9, Fig. 9, are arranged above the wall of the partition 3 and extend along the front wall of the flue to the inlet header 7 of the convectively heated section, part of which forms a closed wall 28 above the partition. The gas temperature may be regulated by passing coal gases from the outlet 30 through a passage 31 into the gases as they leave the combustion chamber. Specifications 313,803, [Class 123 (iii)], 364,981, 367,276, and 384,957 are referred to.

Title: Improvements in or relating to the recovery of metallic values from iron-containing ores or concentrates
IPC: C22B3/08
Filed: 1951-08-10
Abstract: Iron ores or concentrates containing other metals, e.g. nickel, copper, lead cobalt, are heated in a slurry with water at 200-260 DEG C and at a pressure of more than 400 lbs./sq. in., up to 1,000 lbs./sq. in., in the presence of sulphur, which may be present in the ore, and an oxidizing gas, e.g. air or oxygen, until basic iron sulphate is precipitated, which is then separated.  The amount of water in the slurry is such that the concentration of the sulphuric acid formed reaches 15-250 grams/litre.  After removal of the basic iron sulphate, the acid content is reduced to 15-50 grams/litre by the addition of lime, and the partially neutralized solution again subjected to the high-pressure, hightemperature oxidation step to precipitate substantially all of the remaining iron.  Copper, nickel and cobalt sulphates are present in the solution, which may be treated with high pressure hydrogen to precipitate metallic copper, and then crystallized to separate nickel and cobalt sulphates.  Lead sulphate is precipitated with the basic iron sulphate.ALSO:Iron ores and ore concentrates containing also nickel, copper, cobalt, lead &c. are treated by a process which produces a solution of nickel, copper and cobalt sulphates, (see Group III), from which metallic copper is precipitated by high-pressure hydrogen.

Title: Method for the production of acid-halides of penicillin
IPC: C07D499/28
Filed: 1953-07-09
Abstract: Penicillin acid halides are produced by reacting a penicillin salt with a phosphorus halide or thionyl chloride in an inert organic solvent for at least 24 hours at - 20 DEG  C. to room temperatures. The pH during reaction is maintained at 4 to 6 by the addition of an organic base such as pyridine.  Specified phosphorus halides are phosphorus trichloride, phosphorus pentachloride and phosphorus tribromide.  Inert organic solvents are aliphatic chlorinated hydrocarbons such as methylene chloride, ethylene chloride and chloroform.  The acid halide is recovered from the reaction solution by precipitating impurities by means of ether, filtering and precipitating the acid halide by the addition of an aliphatic hydrocarbon such as hexane or petroleum ether. The ether precipitate contains quantities of the acid halide which are recovered by dissolving the precipitate in acetone or chloroform and then adding isopropyl ether, petroleum ether or hexane to precipitate the acid halide.

Title: Improvements in the manufacture of esters of cellulose
IPC: C08B3/00
Filed: 1947-07-17
Abstract: Cellulose is substantially completely esterified in the presence of an inorganic acid catalyst under conditions such that a primary cellulose ester is obtained; to the solution there is added a neutralizing agent, other than an alkali metal or ammonium compound, in an amount at least equivalent to the total amount of inorganic acid employed in the esterification; ammonium bisulphate is added to the neutralized solution, preferably in a proportion of 3-10 per cent of the weight of the cellulose, and the cellulose ester is ripened in the solution at a temperature above 60 DEG  C.  Secondary cellulose esters of good stability are thus obtained.  The neutralizing agent may be an acetate of magnesium, zinc, aluminium, calcium, barium, or strontium, or strontium oxide or hydroxide, barium oxide or hydroxide, or magnesium carbonate.  In an example, cotton linters are pretreated with acetic acid containing sulphuric acid and water at 35 DEG  C.  The activated cellulose is treated with acetic anhydride, acetic acid, and sulphuric acid cooled to -6.5 DEG  C.  The reaction proceeds for 2 hours, a peak temperature of 43 DEG  C. being reached. At the end of the reaction, aqueous magnesium acetate solution is added to neutralize all the sulphuric acid and provide a 10 per cent excess, and at the same time to convert unchanged acetic anhydride to acetic acid.  The solution is then heated to 60 DEG  C. and then steam is injected until 100 DEG  C. is reached.  Ammonium bisulphate is added and the cellulose acetate is allowed to ripen, the temperature dropping gradually to 90 DEG  C.  After 12 hours, the cellulose acetate is precipitated by adding water.  The process is applicable to the production of cellulose propionate, butyrate, aceto-butyrate, and other cellulose esters.
